Example

The following example shows the usage of java.io.ObjectInputStream.readFloat() method.

package com.tutorialspoint;

import java.io.*;

public class ObjectInputStreamDemo {

   public static void main(String[] args) {

      float f = 1.198743f;
      try {

         // create a new file with an ObjectOutputStream
         FileOutputStream out = new FileOutputStream("test.txt");
         ObjectOutputStream oout = new ObjectOutputStream(out);

         // write something in the file
         oout.writeFloat(f);
         oout.writeFloat(5973.9834f);
         oout.flush();

         // create an ObjectInputStream for the file we created before
         ObjectInputStream ois =
                 new ObjectInputStream(new FileInputStream("test.txt"));

         // read and print a float
         System.out.println("" + ois.readFloat());

         // read and print a float
         System.out.println("" + ois.readFloat());

      } catch (Exception ex) {
         ex.printStackTrace();
      }

   }
}

Let us compile and run the above program, this will produce the following result:
